Specification of Letters Patent.

Patented Jan. 30,1912.

To all whom it may concern:

Be it known that I, CARL Josr, a subject of the King of l lungary, residing at Bombay, India, have invented certain new and useful Improvements in-Air Coolers and Purifiers, of which the following is a specification.

This invention has reference to air cooling and purifying devices of the type in which the air is drawn or forced by a tan or other means over or past a. series of elements of porous material, the latter .being kept constantly moist.

The, objects of the invention are to provide satisfactory means for controlling and regulating the supply and more particularly for efl'ccting such supply of water or other liquid to the porous elqpents and further to provide a compact ant. ellicicnl. cooling and purifying dcvice'whereby air may be introduced into the room to be ventilated at a very low temperature and in a state which complies witlrall hygienic requirements.

The above objects are attained by the device illustrated by way of example in the accompauving drawing, in which two constructions are shown.

Figure 1 is a vertical section, Fig. 2 a back view with one part hroken oil and shown in section, Fig. 3 is a. cross-section on the line A l) of Fig. l and Fig. l is also a cross-section through another construction.

The drawing shows a construction in which a small tan displaces forces or draws the air through a vessel or a series of vesscls or cells which has walls always kept moist, so that the air becomes ,cooled on the.

said walls. and also deposits on them its nupurltlcs such as dust, etc, carried, so that it is intrmlucod into the room to be ventilated at a very low temperature and in a state which (f-UlllPllP with all h \;'gicnic rcquirclnents.

The apparatus comprises two parts which are )l'(?ftl'tll1 l adapted to be separalml for the purpose of examining and cleaning the same. The lml'tonl part 1 of the apparatus which constitutes the cooling and puritying device is provided on one s le with a charging device or tunnel 2 for the cooling water provided with a water gage glass 3. At another point the vessel 1 is provided portion of the plate projecting beyond the same, are glazed at the upper surface or rendered impermeable to water. In the center, the plate 6 is provided with a cylinder 8 open at the top, and at the bottom, the upper edge of which projects slightly from the surface of the plate 6, but not as high as the outer edge 7, in order that the water on the plate (3 should be forced/to flow over into the said cylinder before it rises as high as the edge 7. The cylinder 8 is provided with" ribs or other means such as grooves 9 between-which can he guided downward a roller 10 or a rod rounded off i at the bottom made of stoneware or some other suitable material. Around the cylinder 8 concentric cylindrical walls 11 are arranged connected to the upper plate 6 and forming passages open at thebottom. At one point all the cylinders 11 are connected together by means of a partitionlB, and the cylinder walls. including the central cylindcr 8, are alternately provided at one or at the other side of the partition 12;, with passage openings as clearly shown in Fig. 3. in the vessel, water is contained up to a certain level so that the air entering the vessel 1 through the opening 4-, has to follow the loug path. indicated by arrows in 3 through all the circular passages, beforeit can pass into the central cylinder 8 and escape at the top. The water contained in the vessel '1, is drawn in by the cellular element, so that the walls are always keptmoist. In order to insure this throughout the whole height of the walls, the upper surface of the plate 6 isalso provided with water by means of the device hereinafter described, so that the water in question passes from the top into the porous Walls.

Fig, l of the drawing shows 'a construction of the cellular clement comprising a single wall of spiral form, so arranged that the inlet to the spiral is near the wall of tral diameter of which must 10 arranged in. the central. portion c. body it) may be adaptcd to participate in wvatcrto besupplied to the 1,

llic vessel, and tho outletilrom the spiral. in llll) ccntcr, in which cuss the central cyliudcr nced not be complete, 011 the outer 'l'rcc 1' or annular llauge oi the plate B is car led a boll mouthed tube 13 which rotatable with. the cellular clcmcnt, so that its opening can tucc every Way. tan l5, driven by an clectrlc .uiclor ll is mounted to work in the opcning of the bell mouth. lustead of an electric motor adriven in any other manner could be uscd. The motor let is preferably secured to the bell mouth, and the attachment parts carry attlio outside a switch 16 and terminals or a plug conncction 17. The motor spiudlc is provided at a point above tlic central portion 8 of the cellular clement, with pullcy ll, the cenbcvcry small, but the odgcs of which bvc o. considerably larger diameter is intended to oizcrt centrifugal action. (Ever the pulley is .LU placed an endless bslt, cord or chain 19, made cl suitablc mzutcri l 71; wool, silk, rubber, metal or tire is band or coud traveling vcry slovi'lv o i. to the small diiuletcr of tho pulley, pa the other end loosely croun 11c roller body The the rotation or be fixed, though preferably it should be adaptt-id to be moved up and down. Thc'cord l9 is iutcndcd to raise the ater from the vessel to supply it to the. upper plate 6 of the cellular element. The speed oi the cord 19 and its Water con-- veying capacity are calculatcd so 5 at. it carries upward cizactly as much Water as is consiuncd tlicre by evaporation and by absorption by the cellular clemcnt. In order to colldct tlic Water discharged by tho cord l9 on to tho pulley l8 and again projcctcd by the latter, to transfcfc it to the upper plate (3, there is fixed on the up per platcti a ll-sliapcd casing 20 made of plate or other suitable material, the upper portion of which surrounds the pulley 18 in such manner that the Water projectedis guided downward in the groove. The fan blades 15 draw in air through the conduits the cellular elcmcnt and the opening 4. The air is therefore caused to travel. a long path between the moist cell walls ll and. is therefore cooled to a low temperature and also finds an opportunity to deposit inrpurities, etc. The fan can act also so that the air is forced through the conduits.
